Log Message:

Update to 0.18.0

  Several new variables are introduced:
    - LUA_LMODDIR and LUA_CMODDIR - installation directories
      for Lua modules written in Lua and C.
    - MKC_VERSION is now documented.
    - MLINKS now works just like in NetBSD.
    - CFLAGS.warns.<cctype>.<warn-level> and
      CXXFLAGS.warns.<cctype>.<warn-level> are now documented.
      Feel free to set them in sys.mk before installation.
    - WARNERR for forcing warnings to be reported as errors.

  New targets are introduced: bin_tar, bin_targz, bin_tarbz2,
     bin_zip and bin_deb for creating archive files or .deb
     package containing an installation image (Ex:
     examples/hello_files).  This also introduces new variables: TAR,
     GZIP, BZIP2 and ZIP.

  Documentation:
    - Just a few notes about cross-compilation in mk-configure.7
    - New slides, fixes and improvements in doc/presentation.pdf
    - README: feel free to edit sys.mk before installation
    - README: a few notes about tools used for development.

  Support for POD (Plain Old Documentation) is added
    (.pod.1, ..., .pod.9 and .pod.html suffix rules).
    New variables for this: POD2MAN, POD2MAN_FLAGS, POD2HTML
    and POD2HTML_FLAGS. Ex: examples/hello_xxzip

  ../Makefile.inc is included automatically if exists just like
      in NetBSD. Ex: hello_superfs.

  .ORDER: installdirs install. This should fix -j<N> problem.

  WARNS: add support for HP-UX C/C++

  all:${FILES} ${MAN} etc. for the case when FILES are generated.
     Thanks to Jan Smydke.

  New examples (regression tests): hello_superfs, hello_xxzip.
